Balance and low centre of gravity, terms used in the automo. tive industry, express the aume meaning as "inherent stability," a phrase used to describe the qualities of aeroplanes in fight.

Contributing to this stability, balance and low contre of gravity have long been, recognized by automotive engineers as an import- ant factor in the safety of modern motoring.

When sharp turns must be made unexpectedly, when it is necessary. to sworve suddenly to, avort accident, or when a car is forced part way into a ditch on the rond. side, a low contre of gravity and a good car balance become vital factora.

According to Choster N. Weaver, Studebaker-Eraking distributor at San Francisco, a series of tests made recently by experimental engineers at Studebaker's proving ground furnished amazing proof of the success of engineers In achieving an

It was found that the angle ranged from 63 degrees with the Erskin Sedan to 65 degrees for the President Eight.

AUSTIN

SIXTEEN

The economy of operation and upkeep of the Austin sixteen makes a strong appeal to the motorist who requires a six's manifold advantages, but who cannot or does not care to pay too heavily for the privilege. The pleasing lines and excellence of finish of the coachwork are well calculated to delight those who place great store by appearances, whilst the riding comfort and ease of control are all that the most critical owner could desire. Flexible and silent, the engine pos- sesses vivid acceleration and a turn of speed which makes the car a sheer delight to drive.
